摘要
根据栾川县山洪灾害调查评价项目要求,对栾川县历史山洪灾害情况和典型场次历史洪水进行了现场调查。搜集整理了1949年以来发生的历史山洪灾害记录,对具有区域代表性的典型场次洪水,按照历史洪水调查相关要求进行现场调查,考证洪水痕迹,对洪痕所在河道断面进行测量,并收集调查相应的降雨资料,估算洪峰流量和洪水重现期。为研究典型流域小流域暴雨洪水计算理论方法提供了基础资料支撑,也为全国山洪灾害调查和分析评价工作提供借鉴。
According to the requirements for flash flood disasters investigation and evaluation projects,the flash flood disasters and typical flood events in the history of Luanchuan County were investigated. This paper collected the records of historical flash flood disasters since 1949. The tasks include: regional representative and typical flood events investigation,flood tracks measurements at river cross sections,rainfall data analysis,peak discharge estimation,and flood return period determination. This paper provides basic data for study typical rivers in small watershed and demonstrates storm flood computation theory to improve capacity on analysis and evaluation of flash flood disasters nationwide.
